LOCK AND FASTENER.

Specification of Letters Patent.

Patented Sept. 7, 1909.

Application filed September 15, 1908. Serial No. 453,208.

To all whom it may concern:

Be it known that I, JAMEs ROBERTSON, a

certain new and useful Improvements in Locks and Fasteners, of whlch thefollowing is a specification.

My invention is an improvement in looks and fasteners and consists incertain novel constructions and combinations of parts hereinafterdescribed and claimed.

Referring to the drawings forming a part hereof-Figure 1 is a a frontview of the improvement partly in section; Fig. 2 is a similar view withthe cover plate removed, showing the fastener in locked position. Fig. 3is a similar view, the locking device proper being shown in section.Fig. 4 is a section through a portion of the door, and the lock in placeshowing the sliding bar in one position. Fig. 5 is a portion of Fig. 4showing the bar in another position. Fig. 6 is a longitudinal sectionthrough the locking device proper. Fig. 7 is a view at right angles toFig. 6; Fig. 8 is a view similar to Fig. 7 showing the fastenerunlocked; Fig. 9 is a detail of the night latch arrangement; Fig. 10 isa similar view, and Fig. 11 is a detail perspective view of the meansfor preventing the operation of the key.

The present embodiment of the invention comprises a tube 1, adapted tobe passed through an opening in the door 2, and provided at one end witha flange 3, which flange abuts against the adjacent side of the door. Asliding bar 5 is movable in the tube, and knobs 6 and 7 which may beintegral with the plates 8 and 9 are secured to the door on each sidethereof, by means of screws 10 traversing the plates and the door.

Each of the knobs is provided with an opening therethrough for receivingthe sliding bar, and the knob 6 is provided with a depression 11 in itsface, into which depression projects the end of the sliding bar which isround to form a push button 12. The other end of the bar is slottedlongitudinally as at 13, and the sides of the bar upon each side oftheslot are corrugated as at 14, and a plate 15 provided with anintegral trigger or catch 16 is clamped to the bar by means of a secondplate 17 arranged on the opposite side of the bar and secured to thefirst plate by a screw 18. The bar is also provided with notches 19 uponeach 9 side thereof, at the opposite end from the trigger or catch, andadjacent to the knob 6 for a purpose to be presently described, andadjacent to the plate 9 the bar is provided with a V-shaped notch 20, inwhich normally rests a ball 21.

The ball 21 is in engagement with the upper edge of an opening in an arm22, which is pivoted as at 23, beneath a plate 24 arranged transverselyof the door and secured in place by screws 25, the outer end of theplate being flush with the edge of the door as shown in Figs. 1, 2 and3. The swinging arm 22 is provided at its free end with a pin 26, whichprojects through an are shaped slot 27, in the plate 24, the free end ofthe pin engaging a slot 28 in a radial arm 29,

projecting from a ring 30 which is mounted to rotate on a bushing 31,integral with the plate 24 and projecting beyond the edge of the door asshown in Figs l to 3. The bushing 31 is provided with opposlte openingsin which are mounted balls 32, which balls are adapted to engage anannular recess 33, in a pin 34 secured to the casing 35 of the door, inany suitable manner, and the ring 30 is provided with depressions 36 forreceiving the balls 32, when the rlng is turned in a certain position,and

when the ring. is in this position, and

the door is opened, the edge of the annular recess in the locking pinwhich is inclined as shown in Fig. 6, engages and moves the ballsoutward into the recesses, thus permitting the pin to be withdrawn fromthe ring. It will be evident from the description that when the slidingbar 5 is moved in either direction, either by pressing on the end '12,or by pulling or pushing on the catch 16, the ball 21 w1ll be lifted bythe inclined edges of the notch 20, which in its upward movement Wlllmove the swinging arm'24 to partially rotate the ring 30, whereby tobring the recess in the ring, in position for the balls to movethereinto, to permit the pin to be withdrawn from the ring, and the doorto be opened.

lVithin the plate 9 is arranged a bushing 37 which encircles the slidingbar, and

whose outer end is closed except for a slot 38,

through which passes that portion of the sliding bar between the notches19, as shown in Figs. 4 and 9. The inner end of the bushing is providedwith an arm 39, provided in its free end with a pin 40 in engagementwith a notch 41, in a swinging plate 42,

which is pivoted in the plate 9 before mentioned, the swinging platebeing engaged by a lug 43, on a knob 44, journaled in an opening in theplate, the knob being on the outer face of the plate, whereby'the platemay be swung to oscillate the bushing, so that the transverse slottherein, no longer corresponds with the widest dimension of the slidingbar, whereby said bar is prevented from endwise movement.

A spring 45 is provided on the plate, one end of which engages the pinon the arm, and the other the lug, to retain the arm and plate in theiradjusted position.

It will be obvious from the description, that when the bushing isoscillated by the knob 44 into the position shown in Figs. 3 and 9, thesliding bar will be prevented from endwise movement, for which reasonthe swinging arm 22 cannot be operated by the sliding bar. When thelock. is in this position, it is arranged for a night latch, and may beopened by a key.

The door below the opening for the tube 1, is provided with an openingin which may be arranged the chamber 47, of a Yale lock, whose bolt 48extends through the opening and is connected with a cam plate 46,against whose fiat edge rests the fiat edge of a ring-47 having on itsopposite side a lug 48, which engages a notch 49 in the swinging arm 22before described.

When the lock is arranged in the night latch position, a key inserted inthe lock will turn the bolt 48 to turn the plate 46 into the positionshown in Fig. 1, thereby elevating the ring 47 and swinging the arm 22whereby to open or. release the lock. If desired, the operation of theYale lock may be prevented by a cam 49, arranged within the ring 47*,and mounted upon the end of a pin 50, extending through the plate 9, andprovided on its outer end with a button 51, whereby to manipulate thesame, and a spring 52 is arranged between the plate and the cam forretaining the cam in its adjusted position.

It will be evident that by turning the cam, into the position shown inFig. 3, the ring 47 cannot be lifted to operate the swinging arm.

A plate 53 is provided with trunnions 54, which extend into the recessesin the bushing 31, before mentioned, the plate extending through anopening in the bushing, and the upper end is headed as at 58, and isadapted to engage a recess 55, in the ring 30 before mentioned.

The lower inner face of the plate is beveled as shown at 56 in Figs. 7and 8, and, the free end of the pin 34 is also beveled as shown in Fig.6. When the door is closed, the free beveled end of the pin will-engagethe plate, thus lifting the same, and permittingthe door to lock. Whenthe door is unlocked the loose ring being swung into the position shownin Fig. 1, the plate drops into the recesses of the loose ring, thuslocking the'said ring in the position shown in the before mentionedfigure, and retaining it in position for the reentrance of the lockingpin.
